Went on a Gila elk hunt with my BIL many years ago. Was watching as he heart shot this bull at 75 yards. It laid down and died right there. I wasn't too sure what to think of that since it was my first archery hunt.
A couple weeks later, on an archery antelope hunt he shoots a buck running flat out at 45 yards. The buck piled up right there. Needless to say we all had to give praise to "the master". Was the most amazing shooting I had ever seen.
Fast forward a couple years. We are at a party having too much to drink. My BIL commented, "You remember that running antelope I shot? Well, I was aiming at the one in front of it."
Point is, long shots or moving shots are a stunt. You are very lucky if things go well.
